To all whom, it 7na7 concern.-

Be it known that I, BERNHARD GRoEDEL VON GYULAFALVA, manufacturer, acitizen of Hungary, and a resident at Gyulafalva, near Kovaszna,Hungary, Austria-Hungary, have invented certain new and usefulImprovements in Devices for Securing and Releasing CradlePosts ofTimber-I/Vagons, of which the following is a full, clear, and exactspecification.

The subject of the present invention relates to a device for use oncradles of-timberwagons. Wagons as usually constructed for transportinglong timber or tree-trunks have each of its two trolleys provided withpivoted cradles in which the upright side posts which confine the timbercan be angularly displaced for the purpose of enabling the timber to beloaded or unloaded without its being required to be lifted over theposts.

The present invention relates to a method of construction of thepivoting and securing arran ements of the post which will almost entirey prevent any load pressing on the pivot of the posts and enable thesecuring device which holds the posts in the upright position to beeasily released by an operator standing at the ends of the wagon, sothat the Wagoner and his assistants are not exposed to the danger oflogs rolling onto them from the wagon when released therefrom, thedevice being also simple in construction and durable.

The accompanying drawings show the new device in various views.

Figure 1 is an end elevation of the pivoted cradle with the post securedin the upright position. Fig. 2 is a side elevation of onehalf of thecradle, showing in dotted lines the post in the inverted position. Figs.3 and 4 are horizontal sections on the lines AA and B B, respectively,of Fig. 1. Figs. 5 and 6 are details of a portion of the construction inplan and side elevation. Figs. 7, 8, and 9 are three views of thereleasing-lever. Figs. 10 to 12 exhibit in various views the method ofapplying the releasing-lever shown in Figs. 7 to 9 to displace thesecuring device of the post. Figs. 5 and 6 show a modification of adetail.

The pivoted cradle a, built up in the usual manner of channel-iron, hasat each end on its upper side a plate I), which is slotted for a portionof its length to correspond to the width of the space separating the twochannel-irons which form the cradle, the length of the slot beingsuflicient to enable the post f to become inverted by rotating aroundthe bolt (1, which bolt at the same time unites the channel-irons of thecradle. The ends of the fork of the slotted plate I) carry buttresses 9,Fig. 6, of which the edges which face each other are inclined, so thatbetween them a wedge-like space is inclosed, the width of whichdiminishes outward. Into this space fits the wedge-shaped projection iof a plate h, which is threaded over the post f and adapted to be slidalong the same By means of this device a substantial bearing is providedto support the post], and the pivotbolt cl is thereby relieved of strainto a great extent. Alternatively the wedge-like plate k can be replacedby a rectangular plate, as shown in Figs. 5 and 6 which would bearagainst the buttresses g 9, but without entering between them. By meansof the wedgeshaped extension i, however, the advantage will result thatthe posts of the cradle can be situated farther away from one anotherand the capacity of the cradle increased, as indicated by the dottedlines in Fig. 5 The same result may also be obtained by forming thebuttresses g directly on the upper surface of the cradle, dispensingwith the connectingplate Z). The plate 72, i is prevented from fallingoff the postwhen inverted by an enlargement on the end of the post.

The post f is secured in the upright position by a pin is, which isthrust through a hole m in the post, situated immediately above theplate I). In order to provide an automatic locking of the pin is, thefollowing device is adopted: In the side of the hole m a slotway n isformed, which is situated so as to be upward when the post is upright.Through this a feather 0 on the pin 1c is adapted to pass when the pinis inserted into the hole in one position. The pin itself is cranked onthe same side as the feather, so that when it has been thrust throughthe hole in the angular position required by the slot n and the feather0 has emerged on the other side of the post the eccentric weight of thecranked pin lc will cause it to turn so that its cranked portion willrest on the upper surface of the cradle. In this position the feather 0will be turned out of linewith the slot n, and the pin will thereby beprevented from falling out.

For the purpose of unloading the wagon, as before mentioned, the post fis inverted. To effect this purpose, the pin 76 after being suitablyturned is withdrawn from the hole m n. Notwithstanding the removal ofthe pin, the post f will remain upright by reason of the interaction ofthe buttresses g g and the plate h under the influence of the sidepressure of the load of timber. In order, therefore, to invert the post,the plate 6, with its wedge end "i, must be withdrawn from engagementwith the buttresses g g. This is effected by means of the lever 29,Figs. 7-9, of which the under side at 9 serves as a fulcrum. This isrested on the upper surface of the cradle or on one of the buttresses g,while its front end r is inserted into the slot between the twochannel-irons of the cradle and engages beneath the plate Z), Figs. 10and 12.

By means of the notch s and the curved shape of the portion between theend 1" and the fulcrum g the lever p can be placed in position androtate on its fulcrum g and on one of the buttresses g in the necessarymanner. The end 1' thereby raises the plate I), which slides with acertain amount of play on. the post until its wedge extension idisengages from the buttresses g, whereupon the post inverts by the sidepressure of the load. As the trucks are always placed near the ends ofthe timber which they carry for the sake of mobility and since with thepresent device the posts are released by an operator standing at theends of the wagon, there can be no danger from falling logs.

The pin is in order to avoid loss is suitably connected by a chain orthe like to the truckframe of the wagon.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is- 1. A device for securing in its operative position, ina readily-released manner, a pivoted side post of the cradle of atimberwagon, comprising a cradlebeam, a post pivoted within the forkedend of the beam, a plate threaded over the post and a buttress in rigidunion with the cradle-beam, which buttress is adapted to resist outwardmovement of the plate, and thereby the post due to the side pressurethereon of the timber.

2. A device for securing in its operative position, in areadily-released manner, a piv oted side post of the cradle of atimberwagon, comprising a cradle-beam, a post pivoted Within the forkedend of the beam, a plate threaded over the post which, on the sidetoward the end of the cradle-beam is wedge-shaped, and a buttress inrigid union with the cradlcbeam, which buttress is correspondinglywedge-shaped to receive the said wedge-shaped side of the plate andresist outward movement of the plate and. thereby the post due to theside pressure thereon of the timber.

3. A device for securing in its operative position, in areadily-released manner, a pivoted side post of the cradle of atimberwagon, comprising a cradle-beam, a post pivoted within the forkedend. of the beam, a plate threaded over the post, a buttress in rigidunion with the cradle-beam, which buttress is adapted to resist outwardmovement of the plate and thereby the post, due to the side pressurethereon of the timber, and a pin having a feather on its point and acranked handle, which pin is adapted to be inserted through a hole inthe post above the plate in one angular position and to precludewithdrawal in other angular positions.

4. A device for securing in its operative position, in a readilyreleasedmanner, a pivoted side post of the cradle of a timberwagon, comprising acradle-beam, a post pivoted within the forked end of the beam, a platethreaded over the post which, on the side toward the end of thecradle-beam, is wedge-shaped, and a buttress in rigid union. with thecradle-beam, which buttress is correspondingly wedge-shaped to receivethe said wedge-shaped side of the plate and resist outward movement ofthe plate and thereby the post due to the side pressure thereon of thetimber, and a lever for releasing the plate, comprising a flat underside which serves as a fulcrum and a projected end and a notch, asdescribed.

In testimony that I claim the foregoing as my invention'I have signed myname in presence of two subscribing witnesses.
